Both Valentino Rossi and Maverick Vinales are still unsure whether some electronics modifications returned them to the MotoGP podium fight or it was a combination of a harder Michelin carcass and a grippy track.
The pair were right on the pace all weekend with Rossi claiming a podium while in the race, Vinales was able to bag third behind Marc Marquez and Andrea Dovizioso with his team-mate in close attendance.
“I believe it is the changes we did on the bike but the rear tyre is also different. For sure it helps us a lot turning the corner let’s see if it is not the rear tyre and if it is the changes we did on the bike,” said Vinales, speaking at the track.
Rossi added: “Now we need to understand how much is this track, or how much we improved the bike. For me, on paper, this track was not a Yamaha track. I expected to suffer a lot more and to be, for example, stronger in Misano. But in Misano we struggled. So it’s difficult to understand.
“But we feel better with the bike, me and also Maverick are strong. Maybe we improved a little bit, but now we have to see in Motegi. For me, more than the layout of a track, it’s the difference in the grip of the asphalt that helps us more or less at the moment.”
Yamaha have appointed WorldSBK electronics guru Michele Gadda to Head of Electronic Control Group and he has already been making changes, along with a Japanese counterpart.
